<a name="spectrum"><font color="#FF0000">[1]</font></a> plot area<br>
- place where will be plotted all the data and results<br>
<p> 

<a name="grid"><font color="#FF0000">[2]</font></a> grid axes<br>
- place where will be plotted the grid, mask, contours, location of stations, location of loaded files and coastlines<br>
<p> 

<a name="output"><font color="#FF0000">[3]</font></a> output area<br>
- place where output of analysis will be displayed; every line got data from one frequency;<br>
only the first ten (more significant) will be displayed in case of FSA<br>
a mouse click on each line will plot a maker on the selected frequency; in case of 2D analysis and ellipses are plotted,<br>
 first click will select the proper ellipse (hiding all others), second will make it bold and third will give it back as default<br>
